SHEA CARRIER FOR BINDERS.

Application filed August 23, 1922. Serial No. 584,876.

I '0 all whom it may concern Be it known that I, HOWARD M. JOHNSTON, ofthe city of Toronto, in the county of York, Province of Ontario, Canada,a subject of the King of Great Britain. have invented certain new anduseful Improvements in Sheaf Carriers for Binders, of which thefollowing is a specification.

This invention relates to attachments for harvester binders adapted tocatch and temporarily hold a plurality of sheaves as they are dischargedfrom the binder deck, and my object is to devise a carrier which willclear the ground under any working conditions of the machine, which willemploy a minimum number of fingers and yet will catch any sheafdischarged and during any longitudinal adjustment of the binder deck,which is particularly adapted to carry sheaves when the binder isturning corners to avoid the sheaves being discharged where they areliable to be trampled on at the next round of the machine, and which isuseful also on the straight where a tendency exists to discharge sheavesat irregular distances.

I attain my object by means of the con struction hereinafter describedand illustrated in the accompanying drawings in which-- Fig. 1 is an endelevation in outline of a harvester binder provided with my improvedsheaf carrier indicated by dotted lines in its sheaf receiving positionand in full lines in its depending position;

Fig. 2 a plan View of parts of the carrier mechanism in its dependingposition and on a larger scale;

Fig. 3 a plan view of part of the same, partly in section and showingthe fingers in their receiving position;

Fig. 4 a detail in end elevation of Fig. 2 of the same showing one ofthe fingers in a depending position; and

Fig. 5 a similar view of Fig. 3, the finger being shown in a sheafreceiving position.

In the drawings like numerals of reference indicate corresponding partsin the different figures.

1 is the fixed frame of a harvester binder and 2 the frame carrying theknotter mechanism, which is adjustable back and forth to suit the lengthof the grain being cut. This arrangement, being common in the art, isnot illustrated in detail.

On the frame 2 is journalled a shaft 3.

This shaft is preferably square to facilitate the mounting of thefingers 4L thereon. It is therefore provided with sleeves 5 and 5 whichform journals rotatable in bearings formed in the frame 2. At one end ofthe sleeve 5 is formed a collar 6, which engages the outer side of thebearing. At the inner side the sleeve is positioned on the bearing bythe washer 7 held in place by the pin 8 driven through the shaft. At theother end. the sleeve 5 is externally cylindrical and has an arm 9formed thereon by means of which the shaft may be rocked. For thepurpose of rocking the shaft I employ a foot lever 10 of ordinary type,which is journalled on the frame of the harvester binder and isconnected by means of a connecting rod 11 to the bell crank lever 12,also fulcrumed on the frame of the harvester binder. This bell cranklever is connected by means of the connecting rod 13 with the rock arm9.

The fingers 4L arecurved as shown particularly in Figs. 1 and 5 so thatwhen they are extended horizontally to receive sheaves, the outer endsextend upwardly. Each finger is journalled on an axis transverse of theshaft l in a bearing 14 secured to the shaft.

The inner end ofeach finger is bent sub stantially at right angles toform a crank arm 15, this crank arm, however, preferably not lying inthe same vertical plane as the rest of the finger when the finger isextended as shown in Figs. 1 'and5. This angularposition of the crankarm relative to the rest of the finger is best seen'in Fig. 2, thepurpose of the arrangement being to have the inner ends of the crankarms well away from the shaft whether the fingers be in the positionshown in Figs. & or 5. The ends of the crank arms are bent substantiallyat right angles in a direction parallel to the axes of the bearings ofthe fingers, and with these ends is pivotally connected the connectingrod 16. It is evident that by actuating the connecting rod in thedirection of its length that the fin 'ers may be simultaneously swung ont eir journals.

It is desired that a rearward swing of the finger ends shall take placesimultaneously with the dropping of the fingers from the position shownin Fig. 5 to the position shown in Fig. 4. This is effected in thefollowing manner. Preferably integral with the sleeve 5 at the left handside of Fig. 2 is formed a cam. 17. This cam is engaged by a projection18 on the connecting rod 16;

When the shaft is swung up from the position shown in Figs. 2 and 1 tothe position shown in Fig. 5, the projection 18 rides down the cam 17and the connecting rod is moved in the direction of the arrow in Fig. 2,thus turning the fingers on their journals to bring the points thereof,which have been directed rearwardly, to a position in which they aredirected upwardly as shown in dotted lines in Fig. 1 and in full linesin Fig. 5. hen the shaft is rocked in the reverse direction to bring thefingers to the position shown in full lines in Fig. 1 and in Figs. 2 and4;, a coil spring 19 connected at one end to the connecting rod and atthe other to the shaft moves the connecting rod in the reverse directionto that indicated by arrow in Fig. 2 and causes the fingers to swingsothat their points are rearwardly directed.

To take some of the strain off the bearings 1 1, 1 form on each bearingan arc-shaped guide 20 which overlies the adjacent crank arm 15 and iscontacted thereby.

What I claim as my invention is 1. The combination with a harvesterbinder of a shaft journalled thereon adjacent the outer edge of thebinder deck; a plurality of curved fingers having journals journalled onsaid shaft on axes transverse of the shaft; means for rocking the shaftto swing the fingers up and down; crank arms formed on the ends of thejournals of V the fingers; a connecting rod pivotally connected withsaid crank arms; and means for longitudinally moving said connecting rodsimultaneously with the rocking of the shaft.

2. The combination with a harvester binder of a shaft journalled thereonadj acent the outer edge of the binder deck; a plurality of curvedfingers having journals journalled on said shaft on axes transverse ofthe shaft; means forrocking the shaft to swing the fingers up and down;crank arms formed on the ends of the journals of the fingers; aconnecting rod pivotally connected with said crank arms; a projection onsaid rod; and a stationary cam with which said projection engageswhereby the rock arms are moved simultaneously with the rocking of theshaft.

3. The combination with a harvester binder of a shaft ournalled thereonadjacent the outer edge of the binder deck; a plurality of curvedfingers having journals journailed on said shaft on axes transverse of.

the shaft; means for rocking the shaft to swing the fingers up and down;crank arms formed on the ends of the journals of the fingers; guidesconnected to the shaft engageable by the crank arms to reduce the strainon the journals of the fingers; a con necting rod pivotally connectedwith said crank arms; and means for longitudinally moving saidconnecting rod simultaneously with the rocking of the shaft.

1. The combination with a harvester binder of a shaft journalled thereonadate the rock arms to turn the points of the fingers upwardly as thefingers are swung up; and a spring tending to actuate the crank arms inthe opposite direction: to turn the points of the teeth rearwardly.
